The NARAKU 50cc cast iron cylinder kit is an affordable and robust alternative for those looking for a replacement for a damaged cylinder or piston. The power output is somewhat higher than the original barrel. Very good value for money for a good quality replacement cylinder kit. Supplied with gasket set and the original head is retained. Spare parts for this kit can be selected from the collection. When installing the piston rings, please make sure that the "T" or "J" mark indicating the ring stop of the piston ring is pointing upwards. Otherwise the piston cannot be fitted correctly.
